I was thinking of parting with mine. I did some useful measurements with it. I also compared its calibrated response with my Rode NT1A mics and used that comparison to create a more accurate calibration file for the NT1As. Since the NT1As have lower noise & distortion than the UMIK-1, and I now have an accurate calibration for them, I don't need the UMIK-1 anymore and would be happy to sell it. It's in VG to like-new condition with the original box, foam, cable and stand.
PM me if interested.
